removal of pharmaceutical residues from a wwtp effluent: pilot-study

Type of project: Internship

Starting date: September – October 2022

Duration: 3 – 4 months

Location: Wetsus – European centre of excellence for sustainable water technology – Leeuwarden, Netherlands

Project description

Pharmaceutical residues or other micro-pollutants have been categorized as a contaminant of concern in the Wastewater Treatment Plants (WWTPs) effluent. They are not effectively removed in the conventional WTWPs as the WWTPs were initially not designed to remove these micro-pollutants. Their presence can cause severe consequences in the natural water bodies ecosystem despite their low concentrations (ng/L to µg/L).

Biological oxygen dosed activated carbon (BODAC) filters are currently being tested as tertiary treatment to remove pharmaceutical residues from WWTPs secondary effluent. A pilot of the filter is built in the Puurwaterfabriek, Emmen. In this pilot study, the pharmaceutical concentrations, organic and nutrient content, and the biological and physicochemical state of BODAC filters are thoroughly investigated.

Project description


  • Allowed to do experimental work in Leeuwarden, the Netherlands;
  • Background in chemical/biological, environmental engineering or related fields;
  • Experienced with practical laboratory work;
  • Good communication and writing skills in English; and
  • Having a valid driver’s license in the Netherlands.


Your responsibilities and benefits

  • Performing regular sampling to the pilot in the Puurwaterfabriek, Emmen;
  • Performing physical and chemical water quality analysis in the laboratory;
  • Opportunity to contribute to the Netherlands’ national innovation programme to remove micropollutants from WWTPs;
  • You will work in a highly-skilled environment for water research and contact with different topics/people; and
  • We offer a monthly allowance of 200 or 400 €, subject to the personal situation and if you have any European grant (Erasmus for instance).
